ABSTRACT
We introduce a new cryptographic primitive, called insub-
vertible encryption, that produces ciphertexts which can be
randomized without the need of any key material. Un-
like plain universal re-encryption schemes, insubvertible en-
cryption prevents against adversarial exploitation of hidden
channels, by including certificates proving that the cipher-
text can only be decrypted by authorized parties.
The scheme can be applied to RFID tags, providing strong
protection against tracing. This enables post-sale applica-
